Alocasia macrorrhizos [Giant Taro, Elephant Ear Taro, Umbrella plant] is a species of flowering plant in the arum family, Araceae, that it is native to rainforests from Malaysia to Queensland.
Alocasia are distinctly exotic and tropical plants that are increasingly becoming popular in American and European homes as houseplants. They are typically grown as pot plants. The large leaves grow to a length of 20 to 90 cm on long petioles.
Their araceous flowers grow at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles.
